An organ to be transplanted, such as a kidney, can effectively be preserved for an increased period of time by perfusion using a perfusate which is made of a Ringer's solution modified by increasing its potassium ion content to 8-20 meq/liter with a stably emulsified perfluorocarbon compound and dissolved albumin. A preferred concentration of the perfluorocarbon compound, for example perfluorodecalin, is 7.5 to 12.5%(W/V) and that of albumin is 1-8%(W/V) based on the perfusate.
@ A method of cultivating animal or plant cells, which comprises contacting a cultivation liquor having animal or plant cells suspended therein with a liquid fluorocarbon having molecular oxygen dissolved therein while one of the cultivation liquor and the liquid fluorocarbon is present in a continuous phase of the other such that 1 ml of it shows a surface area of about 2 to about 600 cm2.
An oxygen-rich ophthalmic composition characterized in that it comprises oxygen and/or oxygen donor, wherein the amount of oxygen and/or oxygen contained in oxygen donor is 10 mg or above per liter of the ophthalmic composition, or the content of oxygen is at least 90% of the saturated dissolved oxygen, which composition is useful in prevention, alleviation, or treatment of ocular diseases, especially corneal diseases or disorders.

A composition useful for producing a superomniphobic coating on a substrate, the composition comprising a colloidal suspension of a fluorinated siloxane in a non-silicon-containing fluorinated solvent. In some embodiments, the composition further comprises particles of a hydrophobized metal oxide, e.g., silicon oxide, wherein the hydrophobized metal oxide may be fluorinated. In some embodiments, the composition further comprises a non-silicon-containing fluorinated polymer. The invention is also directed to methods for making the above composition. The invention is also directed to methods for using the above-described composition for rendering a substrate superomniphobic. The aforesaid method comprises depositing a liquid coating solution onto a substrate to form a coated substrate, followed by subjecting the coated substrate to a drying step to remove a liquid phase of the liquid coating solution, wherein the liquid coating solution comprises a colloidal suspension of a fluorinated siloxane in a non-silicon-containing fluorinated solvent.
